Eargonomic Acoustic Refinement (E.A.R.) for High Performance These high-end open circumaural headphones use E.A.R. technology for outstanding sonic accuracy and clarity. Sennheiser's innovative "Eargonomic Acoustic Refinement" (E.A.R.) design channels audio signals directly into your ears. State-of-the-art, advanced Duofol diaphragms deliver transparency and minimal distortion, while highly optimized, field-strengthened neodymium ferrous magnet systems yield an excellent dynamic response. A surround reflector creates an extended spatial sound field for the lightweight aluminum voice coils chosen for high efficiency and excellent dynamics. The special diaphragm geometry reduces intermodulation distortion, while highly constant, compressed cellulose fleece reduces total harmonic distortion.
